Spring scarves planning

It’s looking like spring is right around the corner, but it is still cold out, so I want to try pastel spring colors but in a warm chenille scarf. 

I did the warp for 3 scarves, but then found two amazing yarns that I wanted to add: 
(I was at the Madrona arts market place when we went to Fibers ETC at Opera Alley in Tacoma, WA. What an amazing place! Stacks of yarn in tall racks everywhere. Two people could not pass each other without sucking in your breath and turning sideways--there was so much high quality yarn!! )

So, warping front to back, I left a space in the reed where I wanted these accents and added them. Surprisingly there were very few tangles. 
Now to decide which weft to use: 

original warp without
added yarns

                           

                                      accent yarns added
                                             and 5 different wefts tried out

I'm not sure any of the wefts have enough contrast to show up the colors. 
What to do, what to do?

so I finally decided on three different wefts, a very bright yellow green which made into a scarf that matches the bright  green moss growing in my lawn and garden beds everywhere!
then a pale green that matches on of the warp stripes, and last a pale blue that matches a few threads in the warp. It's a very subtle difference in the blue and green.
I didn't take the time to do a Saori- type weaving with many different colors this time.
